    So good I'm buying a second

    • Familiarity: I've put it through the wringer

    I bought one of these three years ago for rock climbing. I use it a lot. Fits over my baseball cap or without it, every other helmet I've worn either fits with a hat or without, not both. This one's super comfy both ways and crazy easy to adjust - no drama. It's nearly time to retire my old one, so I'm buying another of the same. Color choices are different than three years ago, wish they still made the orange one.

    Good for that Mountaineering

    • Familiarity: I've put it through the wringer

    Great fit, literally would wear it for 8 hrs a day 5 days a week. I lived with this helmet on. The ventilation is great with this helmet. Bought the red but hindsight would have gone with the white (for those hot summer days). Got me through many a tight spot feeling safe. Sturdy helmet and visor is a huge plus for rainy days. No complaints this helmet is a second skull.

    Illest Helmet I've Ever Worn

    • Familiarity: I've used it several times


    I got tired of looking like a doofus with the classic Black Diamond half-dome bucket. I wanted something that wasn't as perceivably flimsy as a plastic-covered styrofoam bike helmet protecting my noggin from rock fall (you know the equally-safe helmet I am talking about - the one that makes all us bucket wearers self-conscious on Instagram). Enter the Mammut El Cap.

    I'll talk about safety in a minute, but let's talk about what really matters when making this purchase: how cool you look.

    The El Cap has that nice throw-back visor on the front. That's all you need to know. You'll look like the guy or gal that got into climbing before it was cool - like you are a true first ascensionist throwing irremovable, permanent gear into every feature as you work your way up that never-before-climbed 5.4 route.

    But, then, you pull this baby out of the box and all that sets in is disappointment: what happened to that pronounced visor in the marketing picture? This looks only marginally better than my doofus helmet. At least, that's what you'll send your first route in your new helmet thinking. But, let me tell you, once your partner's photos are thrown up on Instagram, all that doubt will wash away. The visor is there and full on.


    The only concern I had when first working with this helmet (you know, day one) was the lack of flexibility of the straps. Those suckers _hurt_ to adjust. It was bad enough to where I wasn't sure if I wanted: (1) to adjust the helmet even when it was a little loose on my first climb with it; (2) return the helmet.
    Solution to immovable straps: wear the helmet a couple times, sweat all over it, shove it in an alpine pack a couple times and the straps will loosen up enough to where they are adjustable.

    The plastic adjustor on the back of the head strap is poorly designed and a disappointment, for sure. Particularly for what is a totally stylin' helmet.

    - Make sure you properly measure your head before you order it (I used a piece of string and a ruler).
    - Put it through the proverbial wringer. The straps will lose their stiffness and become more adjustable.

    Illest Helmet I've Ever Worn

    Runs Small

    • Familiarity: I've used it several times

    I bought this helmet to replace my BD half dome. I decided on this helmet because it has a built in visor and from the images it looked a little cooler than most of the other bucket style helmets out there (style, safety then style). Initially when I tried it on I thought it was way too small. I have a big head but after a bit of adjustment it fit just right. However if the strapping was any smaller it would not have worked out for me. Overall I'm happy with the helmet just be aware that it does run small.

    A Good Helmet that isn't Petzl Or BD

    • Familiarity: I've used it several times

    I needed a new helmet after retiring my ancient Camp bucket. My list of requirements aren't long. A helmet needs to fit me well and offer adequate protection. The El Cap helmet fits my rather large head well and keeps me cool here in the Utah heat.

    My only complaint is the placement and seemingly loose fixture of the EPS foam. It moves inside the shell a little too much for my liking (when not on my head) and I fear a side impact might not be protected well.

    That said, I trust Mammut quality enough to keep wearing the helmet in spite of my reservations.

    Too Small!

    • Familiarity: I returned this product before using it

    Runs a little small but thanks to Kayla W. at backcountry, hopefully she saved the day with a replacement. We'll see if I get a new helmet tomorrow. I tried to send her this derp picture of me in the helmet to try and assess if it was too small but she passed on getting this photo. Instead she helped me order a new helmet overnight for my trip this weekend. I will be returning this as it look like it should fit a kids head. Hope this derpy photo helps other people decide on the helmet!

    Too Small!

    Haha, great photo.

    If you ordered the 52-57 cm it is definitely the kids size. Previously the 52-57cm was branded as Kid's El Cap. It's no longer branded as such, and the El Cap is just available in the smaller size.

    Which size you have im thinking to get
    The small size which is 52-57
    Cus my head is 55.8
    Would it be too small
    The large size is 56-61 might be too big
    My head has a very complicated size to fit between

    Love It!!

    • Familiarity: I've put it through the wringer

    I currently climb in this helmet and it is amazing. I love the fit and the look. Most helmets make me look pretty durpy but this one is stylin' and high profilin' for my head shape. The only reason I didn't give it 5 stars is I wish the chin strap was longer because I have to buckle below a magnificent beard so I need the extra strappage to get under the woolly beast.

    Comfortable but needs some improvements

    • Familiarity: I've used it once or twice and have initial impressions

    Helmet is really comfortable but front clips are not deep enough if you're trying to hold a headlamp for caving or sketchy night activity. Trying to fit my black diamond icon on this helmet for caving was a nightmare. This will definitely be a great helmet for rock climbing but I'll keep searching for a good headlamp compatible helmet.

    Really nice

    • Familiarity: I've put it through the wringer

    the helmet fits really well and looks great. I especially like the little lip on the front that prevents water from dripping on your face. The harness slides back into the helmet when not in use and the helmet bag protects the helmet when not in use.

    Snowboard Mountaineering/Summer Climbing

    • Familiarity: I've put it through the wringer

    Great Helmet, would highly recommend for anyone who needs a versatile summer/winter helmet for mountaineering. Easily adjustable to fit a winter hat and or a summer baseball cap. Would not recommend for resort usage.

    Noggin > sexiness

    • Familiarity: I've put it through the wringer

    Very nice basic helmet, finish is great for applying stickers (lots of people have this helmet, and if you don't want to accidentally swap head sweat I recommend labeling yours!). Highly recommended for climbing outside

    Drain bamage

    • Familiarity: I've put it through the wringer

    I bought this helmet because I thought it would make me look cool as it turns out nothing makes me look cool. But its still a great helmet and I use it all the time.

    Look good while you stay safe!

    • Familiarity: I've put it through the wringer

    Where to begin on this amazing helmet?


    Can a helmet have style you ask? Oh hell yeah it can! The El Cap has a slight brim which makes it very sleek looking. I really enjoy the matted look this helmet has--I have it in white, and my buddy has it in blue and we both love how the color is a bit subdued.


    The helmet fits snug and is very straightforward with its slide headband. Other helmets have turn knobs and ways to tighten them that are not very intuitive. The El Cap is very easy to adjust before, during, and after your climb.

    As a woman, I find it easy to fit a low ponytail under this helmet without it being uncomfortable and your hair is totally out of the way.

    I have used this helmet on sport leads, canyoneering, and working at challenge courses.

    All around quality product!

    Comfortable and All-around Solid Helmet

    • Familiarity: I've put it through the wringer

    A close call my belayer had with a falling rock I dislodged finally scared me enough to get a helmet. I did some research and compared different products but I'll admit one reason I got the El Cap was because I thought it looked cool.
    After using it regularly for a few months I couldn't be happier with the purchase. First of all, it looks as good in person as it did in the pictures, but more important than that, it's super comfortable. I'm the type of guy who usually hates helmets of any sort but this fits great and I never even notice it's on my head. It's also a breeze to adjust (as other reviewers said, it runs small. I've got a tiny head and the larger size fits me great). I've thankfully never had to really test this helmet's strength, but after several bumps against the wall, there's hardly any sign of wear. Furthermore, I do a lot of night climbing and the clips have worked great so far with my Petzl headlamp.
    All in all, the El Cap is a super comfortable helmet that I'd recommend to anyone and will likely purchase again should this one need replacing.

    Comfortable and All-around Solid Helmet

    Worth the cash

    • Familiarity: I've put it through the wringer

    Scared myself into buying a helmet after a close call with falling rocks, I didn't do much research and thought "hey this looks nice." Later I bemoaned the extra money compared to a Petzl, but I've found the additional features and cool points to be worth the extra. Aside from that the hard shell is way nicer than i was expecting, its pretty scratched at this point, but where a lighter foam only helmet might be trashed this is still trucking. My only problem with it is that I've got a pretty good mane of hair going and it gets real sweaty on hot days, doubt that would be different with any other helmet though.

    Unanswered Question

    Has anyone tried this helmet on wearing belay glasses at the same time?Any hindrance from the visor on the vision on the glasses?

    I just bought this helmet on steep and cheap in the smallest size (56-61). The straps seem to fit my head comfortably, but as one of the reviews pointed out, it looks like a child's helmet-- the shell is tiny! I'm not very familiar with fitted helmets or how this helmet should fit. How much of the back of your head should be covered by the shell? If anyone has pics of a good fit for this helmet, that might be helpful.

    Best Answer

    Hi, the smallest size should be 52-57 cm I believe. 56-61 is the larger helmet; however, you're right. The fit on the small one is WAAAAAY off. You should let Backcountry know and exchange it for the larger size. My head was 55 cm, but the larger one fits MUCH better on me. This is just a picture I found on google, but the fit looks good here. The small one sits way high on the head and is very tight--not good.

    So apparently this isnt a very popular...

    So apparently this isnt a very popular helmet?

    At this point, I think you're right, but based on the fact that it's a relatively new helmet and also hard to find in stores to try on. Here's a link to a Backpacker magazine review,

    I just tried this helmet on at a local shop. It's extremely comfortable. I currently have a Mammut skywalker 2, that I seriously considered swapping out for this. The one thing that stopped me however was that the clips for a headlamp are very small and feel very fragile. To be honest I think they would probably break or lose their strength to keep the headlamp on after a few uses. My other concern was the visor. If you fall, that edge is going to catch and your face is going to go right into the rock or snow/ice. Just something to consider. If you don't plan on using a headlamp with this helmet then I would definitely recommend it.
